SDR and wefax

[PaddyB]

Could be well worth looking at SOX, I've had that running a funcubedongle before,just record the audio live then do what you want afterwards. The opencpn wfax plugin will accept an audio file as input, not receiving and decoding at the same time uses a lot less resources.

Good point. However, it also requires user interaction, which is where I’ll usually mess it up. I’ve long be a proponent of automating tasks to remove the errors of the human element.

Node red can automate the record.

To be honest, the only problem I have with this solution you're proposing is the part when you propose recording the audio live...I think this could easily fail when doing it because of  different factors.

I developed the weather fax plugin and tested a few times using an upconverter. The sdr path for weather fax decoding is not all that well tested though, and I don't know anyone using an upconverter. So yes, if you can record to a file first and get it to work in the plugin, then it can definitely work in the plugin with automatic schedules, there is likely just a parameter not set right or something like that..

Again, I have not used direct sampling. Is extracting the relevant audio the same?
